Can I access ACConfiguration of an ac plugin from another mip plugin?

Or is there any way to share configuration with ac plugin to normal MIP plugin?

Unfortunately there is no way to access the cofiguration. However it is possible to read door and options through the ConfigAPI sample, please see this link, I hope it would be helpful –
